…very rarely is there found candour enough in the human breast, for a man to recede from opinions, for the defence of which he has drawn his pen, and been highly applauded, however strong and demonstrative be the evidence to the contrary that is presented to him. (Theophilus Lindsey, An Historical View of the State of the Unitarian Doctrine and Worship, From the Reformation to Our Own Times, p. 175)
Sad but true.
I must add, though, that one should be very careful in wielding this charge. In the context Lindsey is unfair; he makes this remark about a person in a dispute who in my judgment was not simply being stubborn, not ignoring a mass of evidence to the contrary.
We can be too quick to mock politicians (“Flip-flopper!”) who’ve changed their minds about substantial issues. We assume, cynically, that they must be merely saying they’ve changed beliefs to gain political advantage. But how do we know they haven’t really changed their mind, after revisiting the evidence? Case in point: Romney on abortion.
Given how finite and fallible we are, if someone never changes his mind, you can be sure that he just doesn’t think much.

Help James Anderson defeat my defeater for his defeater-defeater.
Here.
(The target.)
What’s all this defeater business? Michael Sudduth explains here.
I do not look forward to the agony.
May all your defeaters be defeated – except the ones you have for false beliefs.

Congratulations to Scott Williams, trinities contributor and newly minted Oxford University PhD in Theology, on his forthcoming paper:
‘Henry of Ghent on Real Relations and the Trinity: The Case for Numerical Sameness Without Identity’, in: Recherches de Théologie et Philosophie Médiévales 79.1 (2012), will be published.
Here is his abstract:
I argue that there is a hitherto unrecognized connection between Henry of Ghent’s general theory of real relations and his Trinitarian theology, namely the notion of numerical sameness without identity.
<gossip>Once some years ago, I was hanging out with a group of Christian philosophers, and the subject of the Trinity came up. One person, a well known philosopher, firmly remarked that “It’s just gotta be modalism.”
I recently shared this story with a Christian philosopher friend. In response, he told me that more recently, he was hanging with a group of Christian philosophers, and one (who is at least as respected as the aforementioned – which is to say, very) opined firmly that Christians should just admit to being tritheists and defend tritheism. </gossip>
My friend and I got a big laugh out of this.
Neither philosopher, by the way, has published yet on this topic. But maybe we’re in for a bumpy ride!
The more I think about this, though, the less funny I think it is. There’s nothing new under the sun, says my darker self. And I recall the words of the dearly departed Christian philosopher William Alston,
It is a well known fact, amply borne out by the history of the discussion of the topic, that as soon as one goes beyond the automatic recital of traditional creedal phrases one inevitably leans either in the direction of modalism – the “persons” are simply the different aspects of the divine being and/or activity – or tritheism – there are really three Gods, albeit very intimately connected in some way. (“Swinburne and Christian Theology,” International Journal for Philosophy of Religion, 41 (1997) , p. 54).
Well, if that’s so, maybe there’s a problem with those traditional creedal phrases! (For his part, Alston rested with a very unsatisfying appeal to mystery.)
I tremendously respect all three of these people – Alston and the two nameless ones – but I dare say that none of the three has fully enough explored all the options.
A poor exchange. Read it first – then my comments.
Where do I start?
First, I suggest we stick with “SER-ber-us” because pronouncing it “Ker-ber-us” fills some people’s heads with images like these. And we can all agree, that is not a good thing.
Last time, I mentioned Bill Craig’s recent public assertion of his Cerberus analogy for the Trinity. Here’s a remix by an Islamic apologist, with snickering commentary by Reformed Christian apologist James White.
I take it White is not a “social” theorist like Craig, but rather a negative mysterian (refusing to assign much intelligible content to the doctrine) – like those Dallas Theological Seminary folks. In that video linked above, he just asserts that Craig doesn’t know what he’s talking about.
This (that he’s a negative mysterian) in confirmed by this follow up video. (Or at his blog.) In the name of just sticking with what the Bible says, he just Continue reading »

The extraordinary early American minister Noah Worcester (1758-1837) fought in Battle of Bunker Hill, made shoes, taught school, served in the New Hampshire legislature, campaigned unsuccessfully for pacifism, and in his spare time, wrote some really interesting philosophical theology. (In my lingo, he’s a subordinationist unitarian.)
Here are some of his thoughts on the subject of worshiping Jesus.
That the Son of God is to regarded as an object of DIVINE HONORS, is so plain from the Scriptures, that it seems extraordinary that it should even have been denied by any one who has admitted the Bible as a rule of faith and practice. …We have express declarations of the will of God. “The Father judgeth no man, but hath committed all judgment to the Son, that all men should HONOR the SON even as they honor the Father.” This is a sufficient warrant for men to give DIVINE HONORS to the SON of God. Angels have their warrant also; for “When he bringeth in his ONLY BEGOTTEN into the world, he saith, Let all the angels of God WORSHIP HIM.” (Noah Worcester, Bible News: Or, Sacred Truths Relating to the Living God, His Only Son, and Holy Spirit, p. 128, bold added)
I agree.
Worcester proceeds to carefully work through many arguments in this chapter with sure-footed common sense and deep familiarity with the Bible. I thought his answer to a common objection to worshiping the Son was especially interesting:
It may still be thought, that if the Son be not the self-existent God, but has been exalted by God as an object of Divine honors, then God has given his glory to another, contrary to his own word. …

Congratulations to trinities contributor J.T. Paasch on his new book Divine Production in Late Medieval Trinitarian Theology: Henry of Ghent, Duns Scotus, and William Ockham, now available in the U.K. I trust he’ll let us know when it comes out in the U.S.
The Amazon blurb, with bolding gratuitously added by me:
According to the doctrine of the Trinity, the Father, Son, and Spirit are supposed to be distinct from each other, and yet be one and the same God. As if that were not perplexing enough, there is also supposed to be an internal process of production that gives rise to the Son and Spirit: the Son is said to be ‘begotten’ by the Father, while the Spirit is said to ‘proceed’ either from the Father and the Son together, or from the Father, but through the Son. One might wonder, though, just how this sort of divine production is supposed to work. Does the Father, for instance, fashion the Son out of materials, or does he conjure up the Son out of nothing? Is there a middle ground one could take here, or is the whole idea of divine production simply unintelligible? In the late 13th and early 14th centuries, scholastic theologians subjected these questions to detailed philosophical analysis, and those discussions make up one of the most important, and one of the most neglected, aspects of late medieval trinitarian theology. This book examines the central ideas and arguments that defined this debate, namely those of Henry of Ghent, John Duns Scotus, and William Ockham. Their discussions are significant not only for the history of trinitarian theology, but also for the history of philosophy, especially regarding the notions of production and causal powers.
You can get it here.
Christians believe in God. And Christians believe in Jesus Christ. How should we think these two (?) relate to one another? Consider this following inconsistent triad:
D: Jesus and God have differed.
N: Jesus and God are numerically one.
I: If any X and Y have ever differed, then they are not numerically one.
One can’t consistently accept all three. If any two are true, the remaining one must be false. (Go ahead: work through the combinations.)
So a thoughtful Christian ought to reject at least one. But which?
I suggest: whichever we have the least reason to believe is true. But which one is that?
We have as much reason to believe I as we have to believe anything.
Suppose I is false. Then we have some X and Y which at some time have differed (e.g. at a certain time this X was hot and Y was cold, X was here and Y was over there, X was awake and Y was asleep, X knew that P and Y did not know that P) and yet are nonetheless numerically the same. That is, one and the same thing (call it X or call it Y) at one time differed from itself – at one time was a certain way and was not a certain way. But this is obviously impossible.
So supposing I false implies a contradiction. I must, then, be true. And once you grasp the impossibility just noted, you can be very sure I is true – as sure as you’re sure of anything.
So I is off the table. It’s down to D or N then. Which should a Christian deny?
Why believe D? The Bible. In the Garden of Gethsemane, we are told, Jesus didn’t want to die, but God wanted Jesus to die. (Jesus prays to God hoping to change his mind, but eventually acquiesces in God’s will for him.) Or: traditional catholic theology. God is triune; Jesus isn’t triune. Continue reading »
A few thoughts on re-reading Sudduth’s open letter explaining his conversion.
Saith Sudduth,
Krishna is the all-attractive Absolute who is manifested in the different religious traditions of the world. There is merging into impersonal Brahman. There are also distinctly theistic experiences in which the self encounters a personal God.
The ultimate being is either personal or not. Thus, it can’t be that both the aforementioned experiences are veridical, i.e. represent God as God really is.
I think Sudduth agrees; he goes on to explain that “merging” experiences are something like the devotee coming in contract with what some would call the “energies” of God. Of course, Indian philosophers like Sankara would disagree. And I don’t know why we should accept Sudduth’s claim that:
…that transcendental consciousness (the aim of nearly all religious traditions) is in fact variegated in nature.
I don’t know that there is any one general sort of experience which nearly all traditions aim at. Experiences of a loving god are not at all like the sorts of experiences monistic types profess, wherein, they say, Continue reading »
Given my scholarly interests in Hinduism, I had to post a link to this story about the conversion of a Reformed Christian philosopher to a form of Hinduism.
Pictured here are Krishna and his lover Radha. I take it that in Sudduth’s form of Hinduism Krishna is an avatar of Vishnu. Other Hindus consider Krishna to be the high god himself.
There is much art celebrating the love of these two.
The story for me was a bit spoiled when I watched a documentary in which a Hindu, Indian man explained that (at least on some versions) Radha is married to another, and is Krishna’s aunt. Perhaps some would object that I’m not looking at it metaphysically enough.
In another famous episode, Krishna charms a bunch of cow-herding ladies.
I’m curious to read more about Sudduth’s conversion. How does one get from Calvin’s all-determining triune deity to Vishnu? I wonder if it is by way of fairly mainstream trinitarian modalism…
Myself, as I read Sudduth’s interesting narrative of his conversion I’m not sure where, i.e. with what sort of Christianity, he was starting from. I too have taught the Gita in an academic setting, but I have not had experiences like this:
Around 4:20am (Friday morning) September 16th, I woke suddenly from a deep sleep to the sound of the name of “Krishna” being uttered in some way Continue reading »
The poll below is an interesting one. (The bogus one to the left is only fun, but not interesting.) As I write this post, it is still current, and is available for voting at the upper right of the main blog page.
Which of these is false?
One option is to vote that none are false, since all are true. As I write this, 27% have picked this option. But this is a poor pick. This “is” here is the “is” of numerical identity throughout. Given this, it is impossible that all three be true; they are demonstrably inconsistent. (The logical form is: 1. g=s, 2. g=t, 3. -(t=s).) At least one must be false.
Why then do 27% opt for inconsistency (affirming all three)? Continue reading »
A reader emailed to ask me what I thought about the classic patristic doctrine of “eternal begetting.”In his comment on my previous post, Brandon points out that he doesn’t assert the case described there to be a counterexample. Rather, he was wondering why it isn’t a counterexample; he was probing to see my response.
Fair enough. I’ve left the title of the post as is just for continuity with part 1.
The case Brandon described, was an omniscient God, who is both subject and object of knowledge of himself. God as knower is subject of knowledge but not object. But God as object is what is known, and not the subject of knowledge. So, don’t we here have something which is and isn’t intrinsically some way (being self-knowing) at a time? If so, the principle is false.
My response is that there Continue reading »
In a recent post I put forward my own preferred version of “Leibniz’s Law,” or more accurately, the Indiscernibility of Identicals. It’s a bit complicated, so as to get around what are some apparent counterexamples to the simpler principle which is commonly held.
Aside for non-philosophers: philosophers are usually after universal principles, truths which hold in all cases, rather than mere non-universal generalizations, i.e. rough rules of thumb which have exceptions. (An example of the latter: Boys love trucks.) Thus, when a philosophers makes a (universal) claim, other philosophers come along and try to show that it is false with “counterexamples” – real, or even merely possible, examples which show the principle to be false (as it doesn’t apply to them). For example, if someone says that all Texans love tacos, a counterexample to this would be a person who is from Texas and doesn’t like them. Just one counterexample is enough to show a universal claim to be false. When provided with a counterexample, of course, one will often refine, as it were, the original claim (e.g. All native Texans love tacos, or All Texans who appreciate Tex-Mex food love tacos) and the game goes on. This is all in the interest of discovering together what is true and what is false. (In my example, of course, those “refinements” would admit of easy counterexamples too.)
So my principle said, to paraphrase, that for any x and y, x just is (=) y, only if they don’t ever intrinsically differ. (I put this in terms of one having a “mode” at a time if and only if the other also has that mode at that time. Others would call these “intrinsic properties.”)
Here our friend, philosopher and blogger Brandon offered a counterexample, Continue reading »
In discussing the Trinity or Incarnation, I often have an exchange which goes like this:
- someone: Jesus is God.
- me: You mean, Jesus is God himself?
- someone: Yeah.
- me: Don’t you think something is true of Jesus, that isn’t true of God, and vice-versa?
- someone: Yes. e.g. God sent his Son. Jesus didn’t. God is a Trinity. Jesus is not a Trinity.
- me: Right. Then in your view, Jesus is not God.
- someone: But he is.
- me: So, you think he is, and he ain’t?!
- someone: [silent puzzlement]
In this post, I want to explain the part in italics. First: a point of clarification. The second and third lines are important. When many say “Jesus is God” they just mean that in some sense or other Jesus is “divine.” (This could mean a lot of things, depending on one’s assumed metaphysics.) But this sort of person (line 3) understands Jesus to be “divine” in the sense of just being one and the same as God – that Jesus is God himself – one person, so just one (period).
In the italicized line, I’m applying something called Leibniz’s Law, or the Indiscernibility of Identicals. I sometimes put this roughly as, some x and some y can be numerically identical only if whatever is true of one is true of the other. That’s a sloppy way to put it.
In logic, a more precise way of stating it (used e.g. by Richard Cartwright) is:
(x)(y)(z) ( x= y only if (z is a property of x if and only if z is a property of y))
Literally: for any three things whatever, the first is identical to the second only if the third is a property of the first just in case the third is a property of the second.
The basic intuition is that things are as they are, and not some other way. So if x just is (is numerically the same as) y, then it can’t be that x and y qualitatively differ. This seems undeniable.
There are a few problems, though, with the above formula, which any person trained in philosophy may spot. Continue reading »
I’ve been reading some stuff about identity and relative identity lately, in the process of writing something on relative identity versions of trinitarianism. This post is to share some good finds.
In his excellent entry “Relative Identity“ veteran logican and philosopher of language Harry Deutsch says about the best that can be said for relative identity theories – that maybe, arguably, they solve or help to solve various metaphysical problems. See his sections 2 and 4 for these. His section 5 is a penetrating analysis of Geach’s very hard to follow arguments.
Deutsch’s point of view is very different from that held by most philosophers. For this, see chapter 1 of Colin McGinn’s Logical Properties. (NDPR review.) This is more or less the “orthodox” view that most philosophers hold, atheist or theist, trinitarian or not. I largely agree with it, except for its Platonic aspect. I uphold the logic of identity as McGinn understands it, but do not want to commit to the existence of abstracta like relations. I think the truthmaker of a sentence like “Dubya just is George Bush” is going to be a concrete object, the ex-president himself. In this, I’m in the minority; most philosophers find abstracta indispensible.
Another place one can start is Harold Noonan‘s excellent “Identity” entry. He’s an excellent philosopher, and the piece has many virtues; in particular, see his section 2 on Leibniz’s Law vs. substitutivity principles.
The best thing I’ve ever read on identity and relative identity is Continue reading »
This time, the second and final part of our tale. (Part 1.) It features staggering scientific breakthroughs and moderate fool-pitying, so it should be suitable for all audiences.
Bill went on to serve for several decades at the Central Police Station, and often enjoyed regaling guests or fellow employees with tales of the two most confused polygamists he’d run across. “Probably too much of the firewater,” he’d opine, “or else, too much metaphysics!” He even gussied up the stories a bit, making the first feature identical triplets, and the second, two sets of conjoined twins. (In the improved version, the man insisted that he’d only two wives, but plainly, he had four – just, in pairs).
But the young Bill never expected the amazing advances in science that took place throughout his career, and for the most staggering alleged polygamy case he could imagine. In brief, it’d been discovered that Aristotelian-Thomist dualists were correct. Continue reading »
